AMD Ryzen 7 PRO 5755G vs AMD Ryzen AI 7 445 Comparison

The AMD Ryzen 7 PRO 5755G and the AMD Ryzen AI 7 445 represent two distinct design philosophies from the same manufacturer. The 5755G is a desktop processor built for raw throughput, while the AI 7 445 is a mobile chip focused on efficiency. The benchmark data confirms a clear split: the desktop part dominates multi-threaded and compute-heavy tasks, while the mobile chip takes the single-thread crown.

Head-to-Head Benchmarks

The most decisive victory for the Ryzen 7 PRO 5755G comes in data encryption, where it scores 19,450 against the AI 7 445’s 10,519, a massive 84.9% advantage. This is the largest delta in the entire comparison. Integer math also shows a wide gap, with the 5755G scoring 90,270 versus 58,332, a 54.8% lead. These two results alone establish the desktop chip as the superior choice for cryptographic workloads and general arithmetic processing.

Random string sorting favors the 5755G by 39.5%, with scores of 32,771 and 23,488. Data compression follows closely at a 37% delta, as the 5755G records 295,730 against 215,812. The desktop processor also wins the multithread test by 31.7%, posting 23,858 versus 18,115. Extended instructions show a 29.5% lead for the 5755G, and floating-point math is 29% higher, scoring 50,778 versus 39,362.

The remaining wins for the 5755G are narrower. Find prime numbers shows a 3.6% edge, with scores of 58 and 56. Physics is a 4.7% advantage, at 1,022 versus 976. In total, the Ryzen 7 PRO 5755G wins 9 of the 11 head-to-head benchmarks. The average benchmark score reflects this dominance: 49,196 for the 5755G against 26,936 for the AI 7 445.

The AI 7 445 claims only two wins, both in the single-thread category. It scores 3,591 in the single-thread test, beating the 5755G’s 3,366 by 6.3%. This is a meaningful result, as it indicates the newer Zen 5 architecture delivers higher per-core performance despite running at a much lower base clock. The percentile ranking confirms the overall gap: the 5755G sits in the 90th percentile of all CPUs, while the AI 7 445 is in the 79th percentile.

Architecture Differences

The two processors are built on different generations of AMD’s core designs. The Ryzen 7 PRO 5755G uses the Zen 3 architecture with the Cezanne codename, fabricated on a 7 nm process at TSMC. It packs 8 cores and 16 threads. The Ryzen AI 7 445 uses the newer Zen 5 architecture with the Gorgon Point codename, built on a 4 nm process, also at TSMC. It has 6 cores and 12 threads, relying on a hybrid arrangement of Zen 5 and Zen 5c cores.

Cache layouts differ substantially. The 5755G provides 64 KB of L1 cache per core and 512 KB of L2 per core, with a shared 16 MB of L3 cache. The AI 7 445 has larger per-core caches: 80 KB of L1 and 1 MB of L2, but its L3 cache is only 4 MB. This smaller shared pool is a notable handicap for the mobile chip in multi-threaded workloads that benefit from large, fast shared memory.

The memory interface also separates the two. The 5755G supports DDR4 with dual-channel access, delivering a theoretical bandwidth of 51.2 GB/s. The AI 7 445 supports DDR5 and LPDDR5X, also dual-channel, but with a much higher bandwidth of 89.6 GB/s. PCIe connectivity differs as well: the desktop chip offers Gen 3 with 16 lanes, while the mobile part provides Gen 4 with 14 lanes. ECC memory support is present on the AI 7 445 but absent on the 5755G. The integrated graphics are different too, with the 5755G using Radeon Vega 8 and the AI 7 445 using the newer Radeon 840M.

The process node advantage for the AI 7 445 is clear: 4 nm versus 7 nm. This explains its dramatically lower TDP of 28 watts against the 5755G’s 65 watts. The 5755G has a base clock of 3.80 GHz, while the AI 7 445 starts at 2.00 GHz. Both boost to 4.60 GHz. The AI 7 445 is a mobile part on Socket FP8, released in early 2026, while the 5755G is a desktop part on Socket AM4, released in late 2024.

The Verdict

The data points to a simple choice: the Ryzen 7 PRO 5755G is the superior processor for any task that relies on multi-threaded performance. It wins the multithread benchmark by 31.7% and leads in data compression, encryption, and integer math by margins ranging from 29% to 84.9%. Its 8-core configuration and 16 MB of L3 cache provide the resources needed for heavy parallel workloads. The 90th percentile ranking versus the 79th percentile for the AI 7 445 reinforces this position.

The Ryzen AI 7 445 is the better option where single-thread speed and power efficiency are priorities. It wins the single-thread test by 6.3%, and its 28-watt TDP is less than half of the 5755G’s 65-watt TDP. The 4 nm process and Zen 5 architecture deliver higher per-core performance with far lower power consumption. For a mobile platform, this is the correct engineering trade-off.

The average benchmark score of 49,196 for the 5755G against 26,936 for the AI 7 445 is the summary statistic: the desktop part is roughly 83% higher overall. There is no overlap in their intended uses, and the benchmark results confirm each chip excels in its own domain.

Where Each One Wins

The Ryzen 7 PRO 5755G wins in every multi-threaded and compute-heavy scenario. Data encryption, integer math, and random string sorting are clear strengths, with deltas of 84.9%, 54.8%, and 39.5% respectively. Data compression and floating-point math also favor the desktop chip by 37% and 29%. The multithread benchmark shows a 31.7% lead, making this the processor for rendering, compiling, and scientific computing on a desktop system. The physics test and prime number finding are also wins, though by smaller margins of 4.7% and 3.6%.

The Ryzen AI 7 445 wins exclusively in single-thread performance. Its 6.3% lead in the single-thread test indicates that applications relying on high per-core speed, such as lightly threaded games or legacy software, will see a benefit. The lower TDP of 28 watts, combined with the 4 nm process, makes it the only sensible choice for a thin-and-light laptop where battery life and heat dissipation are critical. The higher memory bandwidth of 89.6 GB/s and support for DDR5 also give it an edge in memory-sensitive tasks, even if the overall compute throughput is lower.
